`#[expect]` doesn't work anymore with pre-expansion early lints

[JonathanBrouwer]

The following test passes on stable, but not in nightly:

//@ edition: 2015
#![warn(keyword_idents_2024)]

#[expect(keyword_idents_2024)]
//~^ WARN `gen` is a keyword in the 2024 edition
fn main() {
    let gen = 5;
}

This is very likely caused by: #152369
(why is there no test for this lmao?)

[Bryntet]

This test should just be

//@ edition: 2015
#![warn(keyword_idents_2024)]

#[expect(keyword_idents_2024)]
fn main() {
    let gen = 5;
}

right?

Yes, indeed, oops
